FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 774,997, dated November15, 1904;,

Application filed June 18,1904- Serial No. 213,151. No model.)

To all whom it may concern:

Be it known that I, BURDETTE J. WHITE, a citizen of the United States,residing at Vestfield, in the county of Hampden and State ofMassachusetts, have invented a new and useful Feed-VVater Heater, ofwhich the following is a specification.

This invention relates to an apparatus which is designed to be placed inthe mouth of a boiler-furnace for affording protection to the walls ofthe mouth and at the same time raising the temperature of thefeed-water.

The object of the invention is to provide an apparatus which is verysimple to construct and easy to adapt to various sizes and shapes offurnace-mouths, which effectually reduces the temperature at the mouthof the furnace and efficiently raises the temperature of the feed-water,and which can be applied without making any openings or holes throughthe base plate, so that it will not become cracked or leaky as a resultof expansion and contraction and can be quickly'cleaned to insure a freecirculation of water.

The embodiment of the invention that is illustrated is designed for adouble mouth furnace and has pipes adapted to stand vertically inside ofeach fire-door adjacent to each of the cheek-plates, pipes adapted toextend horizontally between the upper ends of the vertical pipes belowthe arch-plates, and pipes adapted to extend horizontally from the lowerends of the vertical pipes through the lower parts of the cheek-platesinto clean-out pipes that extend to the front of the boiler.

Figure 1 of the accompanying drawings shows a plan of an apparatus thatis designed to protectadouble-mouth furnace and to heat the feed-waterfor the boiler of such a furnace. Fig. 2 shows a front elevation of thesame, and Fig. 3 shows a side elevation.

The apparatus shown has three pipes 1, arranged vertically one behindthe other adjacent to the cheek-plates 2 on each side of each month intothe furnace. Each vertical pipe has a fitting 3 at the bottom and afitting 4 at the top.

The lower fittings of each set of vertical pipes are coupled togetherfrom front to back by pipes 5, and the upper fittings of each set arecoupled together from front'to back by pipes 6, so that each verticalpipe at bottom and top is in communication with the adjacent verticalpipe. The top fitting of each vertical pipe is also connected with thetop fitting of the corresponding pipe on the opposite side of the monthby a horizontal pipe 7. The top horizontal pipes extend across the upperpart of the months just below the arch-plates 8. The vertical andhorizontal pipes form practically three square arches, one back of theother ineach mouth. The lower fitting of each vertical pipe rests uponthe base-plate 9.

Connected with the lower fitting of the back vertical pipe on one sideof one arch is an inlet-pipe 10, that is provided with a cock 11, whichis adapted to be connected with a pipe 12 with the reservoir containingthe feedwater that is to be heated and that is to keep down thetemperature of the mouth of the furnace. The pipe 12 may lead from anysource of water-supply, as a hot-well or pump, or it may lead from thelower part of the boiler.

Connected with the lower fitting of the front vertical pipe on one sideof one mouth is a pipe 13, that extends toward the front and is providedwith a cook 14, which when open permits all mud and sediment which hascollected at the lower ends of the vertical pipes on that side of themouth to be blown out in front of the boiler.

Each of the lower fittings of the vertical pipes at the middle areconnected by pipes 15 with fittings 16, that are connected by pipes 17The outer one of these fittings is connected with a pipe 18, that has acock 19, which when open permits the sediment collected at the bottom ofthe inner vertical pipes and in these cross-pipes to be blown out infront of the boiler.

Each of the lower fittings on the outside of one of the arches isconnected by a pipe 20 with afitting2l. These fittings are connected bypipes 22. From the front fitting extends a pipe 23, which is providedwith a cock 24, that when open permits the sediment collected at thebottom of the vertical pipes on this side and in these horizontal pipesto be blown out in front of the boiler.

Extending upwardly from a middle top fitting of each arch is a pipe 25.These pipes are connected by a pipe 26, and leading from them is a pipe27, which is intended to extend to the boiler above the water-line.

All of the fittings used in the construction of this apparatus may bemade of the same material as the pipes, so that the expansion andcontraction will be equal, and all of the fittings and the pipes may bemade of malleable iron, so that there will be no tendency to crack undervariations of temperature. These parts can be readily procured and canbe easily assembled originallyor can be readily replaced if one part isdamaged ordeteriorates in use.

The apparatus can be conveniently adapted to the mouths of furnaces ofvarious sizes and shapes. It is readily located in place and thoroughlyprotects the mouths and efiiciently raises the temperature of thefeed-water. In placing this apparatus in position it is not necessary tomake openings through the baseplate, and the only openings requiredthrough the crown-plates are the two for the passage of the return-pipesthat lead to the boiler. The pipes can be kept free from sediment andrust by simply opening the valves which are at the front and allowingthe sedimentto blow out with the water from the bottoms of the verticalpipes and the clean-out pipes.

The invention claimed is- 1. A feed-water heater and furnace-mouthprotector having vertical pipes adjacent to the cheek-plates, horizontalpipes extending forwardly and backwardly and connecting the upper andlower ends of the vertical pipes on the same sides. horizontal pipesextending below the arch-plate and connecting the upper ends of thevertical pipes on opposite sides, pipes extending horizontally from thelower ends of the vertical pipes outwardly through the lower portions ofthe cheek-plates, and cleanout pipes extending forwardly from theselatter pipes higher than the base-plate and in front of the boiler beingprovided with blow-out cocks, substantially as specified.

2. A feed-water heater and furnace-mouth protector having vertical pipesadjacent to the cheek-plates, fittings at the top and bottom of thevertical pipes, couplings extendingforwardly and backwardly andconnecting the fittings at the top and bottom of the pipes on the sameside, pipes connecting the fittings at the top on opposite sides,forwardly-extending clean-out pipes higher than the baseplate, pipesextending horizontally from the fittings at the lower ends of thevertical pipes and entering the clean-out pipes, a pipe connected with alower fitting on one side for the inflow of water, and a pipe connectedwith an upper fitting at the other side for the outflow of water,substantially as specified.
